Claims

[Claims for Utility Model Registration] (1) A coil block in which a coil is wound around an iron core formed in a substantially U-shape, and a coil block that is interposed between the magnetic poles of the iron core and has the same polarity at both ends corresponding to the magnetic poles. a permanent magnet whose central part between both magnetic poles is magnetized with different polarities, and a movable contact whose tip faces a fixed contact from the central part of the side of the armature whose central part is pivotally supported. an armature block integrally formed with a spring piece protrudingly formed thereon, and a hinge spring formed integrally with the movable contact spring piece as a fulcrum shaft protruding in a lateral direction from the center portion of the side surface of the armature; A common terminal piece having a common terminal on the upper part which is exposed below the upper surface of the base and fixes the hinge spring is implanted in the side wall of the base, and the hinge spring is used as a fulcrum shaft. In an electromagnetic relay with a swingable armature block, a notch is formed in the side wall of the base and the top and both sides are open, and an adjustment part for adjusting the spring load of the hinge spring is provided within this notch. Characteristic structure of electromagnetic relay. (2) The common terminal at the tip of the common terminal piece is formed into two forks, and the tip of the hinge spring is formed into two, and both tips of the two forks are fixed to each other to support the tip of the hinge spring at two points. The structure of an electromagnetic relay according to claim 1 of the utility model registration claim, characterized in that: (3) Form the tip of the common terminal piece into two,
2. The structure of the electromagnetic relay according to claim 1, wherein only one tip of the crotch protrudes into the notch to serve as a common terminal, and the common terminal and a hinge spring are fixed to each other.
